Online retailer Amazon.com Inc. is expected to build a roughly 1 million-square-foot distribution center in the River Ridge Commerce Center in Jeffersonville, according to state legislators.

The board of the commerce center approved resolutions Tuesday intended to simplify land sales in the business park, and one of the resolutions specifically mentions a 70-acre tract on Patrol Road, near a large building used by the U.S. Census Bureau, that would accommodate such a large facility.
